A far-infrared spectrometer based on cyclotron resonance emission sources

Abstract
Practical realization of the spectrometer based on the cyclotron emission sources is presented. It is shown that it can be used for transmission measurements in the range from 35 to 110 cm−1 with resolution up to 1.3 cm−1. Performances of the spectrometer are demonstrated by its application to the studies of impurity and free‐electron states in two‐dimensional structures.
